20150214850 | Synchronous Rectification Controller and Relevant Control Method - A timing controller provides adaptive timings to control a synchronous rectifier with a body diode. The timing controller has a ramp generator providing a ramp signal at a first capacitor. The ramp signal corresponds to a discharge time when the body diode is forward biased. A second capacitor records an estimated duration signal. An update circuit is connected between the first and second capacitors, for shorting the first and second capacitor to update the estimated duration signal by charge sharing. A comparator with two inputs coupled to the ramp signal and the estimated duration signal respectively compares the ramp signal and the estimated duration signal to control the synchronous rectifier. | 07-30-2015 |
20150214851 | Synchronous Rectification Controller and Relative Dead-Time Control Method - A synchronous rectification control method suitable for a switching mode power supply with a synchronous rectifier is disclosed. A synchronous rectification controller with a first pin is provided. A pin voltage at the first pin is sampled to generate a sampled voltage. After the sampling, a detection current is provided and it flows out of the synchronous rectification controller from the first pin. Digital dead-time control signals are generated in response to the pin voltage and the sampled voltage. The synchronous rectifier is controlled to determine a dead time of the synchronous rectifier, based upon the digital dead-time control signals. | 07-30-2015 |

20160067427 | NEBULIZER AND CONTROLLING METHOD THEREOF - A nebulizer includes a nebulizing circuit, a power circuit, a sampling circuit, a filtering circuit and a controlling circuit. The nebulizing circuit includes a piezoelectric actuator. During operation of the piezoelectric actuator, the liquid is nebulized. The power circuit selectively provides electric power to the nebulizing circuit so as to power the nebulizing circuit. A harmonic signal generated by the piezoelectric actuator at a working frequency is sampled by the sampling circuit. A specified frequency of the harmonic signal is retrieved by the filtering circuit. The controlling circuit controls operations of the power circuit and receiving the specified frequency of the harmonic signal. By comparing the specified frequency with a predetermined frequency, the controlling circuit judges whether the liquid is exhausted. Once the liquid is exhausted, the controlling circuit controls the power circuit to stop providing the electric power to the nebulizing circuit. | 03-10-2016 |

20130194376 | METHOD FOR SWITCHING SHARED CONTENT IN A VIDEO CONFERENCE AND A VIDEO CONFERENCE SYSTEM - A method for switching shared content in a video conference includes determining a status of the video conference when a switch event is triggered. If the status is a video status, sharable content of the sharing terminal are detected, and whether the sharing terminal has at least one sharable content is determined. If so, one of at least one sharable content is shared with at least one remote terminal. If not, the status keeps being in the video status. If the status is a sharing status and the sharing terminal shares a content having a first index number, sharable content of the sharing terminal are detected, and whether the sharing terminal has a first sharable content having an index number larger than the first index number is determined. If so, sharing the first sharable content with at least one remote terminal by the sharing terminal. | 08-01-2013 |
20130212182 | METHOD AND SYSTEM FOR COLLABORATIVELY OPERATING SHARED CONTENT IN A VIDEO CONFERENCE - The disclosure provides a method for collaboratively operating shared content in a video conference, wherein the shared content is shared by a sharing terminal to a shared terminal. In the method, an operation event is transmitted by the shared terminal to the sharing terminal. The operation event is then transmitted to a virtual device of the sharing terminal, and the operation event is performed on the shared content by the virtual device. | 08-15-2013 |
20150161885 | METHOD FOR CONTROLLING WEARABLE DEVICE - A method for controlling a wearable device includes the steps of: providing the wearable device which includes a sensor; detecting and recording movement data relative to the wearable device via the sensor; determining whether the wearable device has triggered a start condition; if the start condition has been triggered, analyzing the movement data; determining whether a user has finished putting on the wearable device according to the analyzed movement data; and if the user has finished putting on the wearable device, determining whether the wearable device is worn on a left side or a right side of the user according to the analyzed movement data. | 06-11-2015 |
